You will want to tip 15-25%wheb you are dining at a sit down restaurant. If you are at a counter service buisness or café, you should only tip of they went out of their way to make your experience amazing. If you will be staying at hotels, you should tip bellmen $3-$5 per bag, concierge 5-10% of what they have procured for you. Cab’s, Ubers, or any car service 10-20% (I usually do a minimum of $5 here.) if you get asked for a tip on any self-service screen, just deny it, that’s a cash grab for the business owner. You can offer a tip to any employee you want if they go out of their way for you, however outside the service industry, employers will direct the staff to politely refuse.
Servers are paid a sub-minimum wage, as tips are supposed to round out their wages. When I wanted tables my paycheck barely covered the taxes on my cash and credit card tips.
